MHINE FOR MAKING EGG-CASE FILLERs.

sPEorFIcATIoN forming part of Letters Patent No. 644,762, dated March e,i900.

Application find Maa 20,1899.-

To` all whom it may; linearm- Be it known that I, JOHN T. CARMODY, acitizen of the United States, residing at Cedar Rapids, in the` countyof Linn and State ofA Iowa, have invented certain new and usefulImprovements in Machines for Making Egg- Case Fillers, of which thefollowing is a specification.

The subject of the present invention is a machine by which the fillersor cells for eggcases are accurately and cheaply made. The s trawboardor other material from which the fillers are to be made is fed tothemachine in as many long sheets as there are to be strips in the iiller,and each of these long sheets is equal in Width to the length of thefiller-strips to be made. The sheets are all simultaneously advanced toa certain position and then arrested until certain operations have beenperformed, whereupon they are again advanced a like distance, and so onintermittently during the operation of the machine. After the sheetshave been advanced and have come to rest they are all simultaneouslyperforated a suitable distance from their ends, and each is severed upona line passing through the row of perforations made at the immediatelypreceding operation of the dies. By thus severing the sheet-s thefiller-strips are cut off from them, and by reason of the describedlocation of the cutl(through the row of perforations made at thepreceding operation of the dies) each filler-strip will have slits ornotches in its opposite edges. For a reason hereinafter described theslits or notches in one edge of the strip extend quite to the centerthereof, while those in the opposite edge are shallower. In order to cuteach of the sheets upon a line passing through the row of perforat-ionsmade at the immediately-preceding operation of the dies, the cutters areplaced in advance of the dies a distance equal to the width of afiller-strip, and by reason of this disposition of the parts at alltimes during the operation of the machine the ends of the sheets in themachine have the described slits or notches equal in depth to aboutone-half the width of the fillerstrip. Each filler is made up of twosets of filler-strips. The sheets from which each set of strips is madeare parallel with each other;

Serial No. 709,817. (No model.)

notches aforesaid being so disposed that they fall at the intersectionsof theisheets. At each operation the sheets are advanced and projectedpast the cutters a distance equal to the width of a filler-strip, and inbeing thus advanced the two sets of sheets will interlock.Simultaneously with the advancing of the sheets two sets ofoppositely-disposed grip ers are also advanced, and at about theiustanthe advancing of the sheets ceases the grippers close upon the advancedand interlocked ends of the sheets, one set of grippers takinghold ofone set of sheets and the other set of grippers taking hold of the otherset of sheets. When the operation of advancing the sheets is completed,they are severed, as alreadydescribed, thus producing the two sets ofpartially-interlocked strips of which the filler is made up. This donethe grippers are retracted, and in being retracted they draw the severedstrips of the two sets toward each other and complete the operation ofinterlocking them. This done the grippers open and recede and an armsweeps the completed filler from its position between the two coperatingsections of the machine. These two sections of the machine are alike inconstruction and operation, each being adapted to complete one of thetwo sets of strips of which the filler is made up and to assist ininterlocking the two sets, with the exception that one section isprovided with the means for operating the arm that dislodges th'ecompleted filler. Hence for the sake of brevity and conciseness thefollowing description will be confined to one section, excepting Whereit becomes necessary to refer to the other, corresponding parts of bothbeing indicated by similar reference characters.

The invention consists in the features of novelty that are herein fullydescribed.

In the accompanying drawings, which are made a part of thisspecification, Figure 1 is a side elevation of a machine for making anvegg-case iiller embodying the invention, a portipn of the base at theright-hand side of the figure being broken away. Fig. l is a sideelevation of a fragment of the base, including the port-ion thereofwhich is not shown in Fig.

Fig. 13 is anelevation of a portion of the mechanism shown in Fig. 12 viewed in thedirection of the arrow 13, Fig. 12. Fig. 14 is a section on the line 1414, Fig. 15, showing on a somewhat-larger scale the mechanism forfeeding the sheets forward, one of the feedtubes, the gripper-operatingframe, the working extremities of one set of grippers, and one of thematrix-bars. Fig. 15 is an elevation of the mechanism shown in Fig. 11viewed in the direction of the arrow15, Fig. 14. Fig. 16 is a plan viewof the gripper-operating frame of one of the machine-sections. Fig. 17is a section thereof and an elevation of fragments of the stems of onegang of grippers. Fig. 18 is an enlarged sectional elevation of adjacentportions of the two sections of the machine, showing particularly thedies, the cutters, the grippers and their accessories, fragments of twofiller-strips partly interloeked and in readiness to be completelyinterlocked by the withdrawal of the grippers being also shown. Fig. 19is an elevation of one of the filler-strips, the position which itoccupies with relation to the end of the sheet before it is severedtherefrom being indicated by dotted lines. Fig. 2O is aplan view of acomplet-ed filler. Fig. 21 is a perspective of a fragment thereof on alarger scale.

On suitable bed-plates A are mounted the two main frames B for the twocooperating sections of the machine, said frames being of quadrantshape, or substantially so. One of these, frames is securely bolted toits bed while the other is hinged to its bed at its outer lower corner,as shown more clearly in Fig. 1, so that it may be moved about its hingeto such position that free access maybe had to its working face and tothe working face of the other machine-section. While in their normaloperating positions the working faces of those two machine-sections areseparated by a space, as shown more clearly in Figs. 2 and 18, which isonly slightly greater in width than the width of one of thefiller-strips, and this space is not sufficient to give access to theparts at the working faces of the two machinesections or adjacentthereto, and hence the necessity for providing means for moving onesection away from the other. In order to facilitate this movement of onesection away from the other, a shaft T/ is journaled to the main frameof the movable section and is provided at one end with a crank T forturning it and at the other end with a beveled pinion T2. rlhis pinionmeshes with correspondinglybeveled teeth on a nut T3, which has athreaded eye and is turned onto a heavy screw T5, the lower extremity ofwhich is pivoted to the base A, as shown at TG. The pinion T2 and nut T3are confined bya yoke T1, the upper branch of which is perforated forthe passage of the screw T". Vith this arrangement by turning the crankT the nut T3 will be caused to turn upon the screw T". The upwardmovement of the nut T3 will be transmitted to the frame B through thepinion T2, its shaft T', and the shaft, bearing, and thus themachinesection to which this mechanism is applied may be moved about itshinge.

The machine shown in the drawings is adapted to make fillers, eachcomprising fourteen interlocking strips disposed in two sets of seveneach. Each of the fourteen strips is cut from a separate sheet ofstrawboard or similar material. The seven sheets of strawboard fromwhich the strips of one set are IOO IIO

IIS

cut are shown clearly in Figs. 2 andifmdJ numbered 1 to 7, inclusive.Each of these sheets is fed forward through a long sheetmetal tube orchute, which is preferably made up of two sheet-metal plates I I, asshown more clearly in Figs. l2, 14, and 15. Both of the plates areattached to the bar F, which carries the matrices of one gang of dies,and, as shown more clearly in Figs. 12 and 14, the plate I' is carriedquite to the forward edge of the bar and is provided with openings 17,registering with the openings of the matrices, whereby the plate I ismade to serve as a stripper for stripping the sheet of strawboard fromthe punches G4. Each of the sheets of strawboard in the section of themachine which is in the foreground in Fig. 1 is represented by a singleheavy line, and the positions of the sheets of strawboard in the othersection of the machine are indicated by the intersecting dotted lines.Each of the sheets is fed forward intermittently by a pair of rolls J j,carried by shafts J j', respectively, the tube or chute being providedin its opposite sides with openings l2, through which the peripheries ofthe rolls are adapted to extend and engage the sheet. The shafts j ofthe rolls j are journaled in short arms projecting from fixed portions 9of the frame, while the shafts J of the rolls J are journaled in shortarms projecting in opposite directions from a pair of bars l0, locatedupon opposite sides of the chutes or tubes and so mounted as to becapable of limited endwise movement for the purpose of relativelyadjusting the rolls of each pair. Thus one roll of each pair isadjustable relatively to its companion, and all of the adjustable rollsbear similar relations to the chutes. In order to enable the use ofrolls of sufficient diameter, the several pairs are arranged in twoparallel rows and staggered. All the shafts derive their movement fromendwise reci procable rack -bars J4, which are mounted in suitablebearings in the frame and are disposed between the two rows of shafts.Rigidly I iXed to each of the shafts, near each end, is a pinion J2, andthese pinions J2 of each pair of shafts intermesh, whereby the shaftsare compelled to rotate in opposite directions, their adjacent sidesalways moving in the direction in which the sheets are to be fed.Rigidly fixed to one shaft of each pair, near each of its ends, is onememberj2 of a clutch, the other member of whichis mounted loosely uponthe shaft, so as to be capable of both rotary and endwise movementthereon,and this movable member of the clutch is held normally inengagement withthe fixed member bya spring 73, interposed between themovable member and a shoulder or collarj4 on the shaft. The movablemember of the clutch is carried by a pinion J 3, which meshes with theteeth of the rack-bar J4. By this means when the rack-bar is moved inone direction it rotates all the movable members of the clutches. Thesein turn rotate the fixed members of the clutches, the shafts by whichthey are carried, and one of the pinions J 2 of each pair, and theselatter in turn rotate the other of the pinions J2 of each pair, and whenthe rack-bar movesin the opposite direction the movable members of theclutches will yield endwise, and thereby permit them to turn upon theshafts by which they are carried, leaving the shafts at rest. By reasonof the fact that the rack-bar is disposed between the two rows ofpinions J 3, and therefore engages the pinions of the two rows atopposite sides, respectively, asto one row of shafts, it is necessary toplace the pinions J3 upon the shafts that are located at one side of thetubes, respectively, and as to the other row of shafts it is necessarytoplace them upon the shafts that are located at the opposite sides,respectively, of the tubesthat is to say, as the parts appear in Figs.2,

14, and 15 as to the vertical row of shafts at the right of the rack-barJ4 the pinions which engage the rack-bar are secured to the shafts thatare above the tubes, while as tothe row of shafts at the left of therack-bar the pinions J 3, engaging the rack-bar, are secured to theshafts that are below the tubes. In other words, referring again toFigs. 14 and 15, the rack-bar J4 is geared to the shafts J of one rowand to the shafts j of the other row. The extremities of the rack-barsJ4 are both connected to a cross-head L, which in turn is hung from ashaft L5, said shaft being in turn supported bylinks L4, carried at theeX- tremities of arms L3, projecting from a rockshaft L', said shaftbeing provided with a crank-arm having an antifriction-roller L2,occupying a cam-groove Ml in the cam-Wheel M. A portion of thiscam-groove is concentric with the axis of the wheel, while the remainderis eccentric, the slope of the cam being about equally divided uponopposite sides of the cams shortest radius, so that during a portion ofthe revolution of the cam-wheel M the rack-bars remain at rest, whileduring the remainder of the revolution they have a uniform to-and-fromovement. The cam-wheel M is secured to a shaft C', which carries abeveled pinion C2, meshing with a corresponding pinion C3 on the mainshaft C of the machine, the latter being provided with a pulley C4 forreceiving a belt. The beveled pinions 03 for driving the shaft C of thetwo sections of the machine are presented in opposite directions inorder that the parts of the two sections shall move in oppositedirections.

The eXtremities of the bars F are rigidly attached to equally spacedshoulders E2, formed on a pair of heavy posts E, which are securelyfastened to a head-plate B of the main frame B and have their upperextremities connected by a heavy bridge-plate E'. As shown moreclearlyin Fig. 12, these heavy bars F carry the matrices or femalemembers of the dies, the male members or punches G4 of which are carriedby heavy bars G, having their ends secured to a pair of rods G',mounted' in suitable bearings, so as to be capable of endwise movement,the bars F being provided with openings for the free passage and endwisereciprocation of the rods. In order to secure the bars G to the rods G',the bars are provided with openings corresponding in diameter to thediameter of the rods, and on the rods between the bars Gare disposedspacing sleeves G3, the ends of which bear against the bars Gand holdthem at proper distances apart, the openings in the bars F being equalin diameter to the spacing-sleeves, so that the latter move freelyendwise with the rods. Each of the rods G is connected with a yoke G",which incloses a cam C5, carried by the shaft C', and the yokes G'l areboth connected bya heavy crosshead H2, having a stem T5 slidably mountedinl a socket formed in a lixed bracket H',

surrounded by a heavy spring I-I, which ex- IOC) IIO

erts its pressure in one direction against the frame of the machinethrough the bracket H and in the other direction against the rods Gthrough the medium of the cross-head H2 and the yokes G. The cams C5 arevery short and are adapted to exert their pressure upon the yokes G",through the medium of antifriction-rollers CG and OT, the ends of theyokes being provided with slots G2 to permit of their necessary movementrelatively to the shaft C. Then the `cams'C5 engage these antifrictiondevices C7, the rods G' are moved in the direction of the arrow in Fig.a and all the bars G thereby advanced, causing the dies to perforate allof the sheets of strawboard, this action being in opposition to theforce of the spring H, and as soon as the cams have passed theantifriction devices CT the spring H will retract the bars G andwithdraw the male members of the dies; or it the spring H is notsufficiently strong the cams will perform this operation when they reachthe antifriction devices C5. IThe bars G are also provided with knivesG5, which, in connection with the edges of the bars F or with plates GGsecured thereto and acting as ledger-blades, sever the projecting endsof the sheets.

rlhe dies are preferably so shaped as to form perforations of the shapeshown in the drawings, or substantially1 so. The parts of the feedingmechanism are so proportioned that at each operation the sheets will beadvanced a distance equal to the width of a fillerstrip, and the diesare so placed with relation to the cutter, that when the sheets come torest after being fed forward the knives will out them upon a lineintersecting the perforations at about the place shown in Fig. 12 of thedrawings and indicated by dotted lines in Fig. 19. The object of this isto provide each ller-strip in one of its edges with al number of deepslits or notches 50, which extend to the center of the strip and whichhave tongues 51 overhangingtheir straight inner portions, the outeredges of the tongues and the opposite edges of the notches or slitsbeing cut ott at an angle for the purpose of providing Haring entrancesto the slits, well adapted for receiving the edges of the strips in theact of interlocking them. In the opposite edge of each strip are anumber of shorter notches 52, adapted to accommodate the tongues 51 ofthe interlocking strips, the sides 53 of these slits being complementaryto the tongues 51, or practically so, so that when the filler is foldedby compressing it in the direction of the arrows in Fig. 20 the notches5:2 will provide clearance for the tongues 51, and thereby permit theiller to be folded flat, or practically7 so.

By reason ofthe described construction and disposition of the twosections of the machines when the sheets are advanced in the mannerdescribed the deep notches or slits in the extremities of the severalsheets carried by one section of the machine will fall opposite the deepnotches or slits in the extremities of the several sheets carried by theother section of the machine, and the unsevered sheets will thereby becaused to interlock, as clearly shown in Fig. 18, where the process ofmaking the Ifiller has advanced to the point of severing thefiller-strips X and Y from the sheets, leaving them supported betweenthe two sections of the machine by the grippers. Dnringthe act ofadvancing, and thus interlocking the ends of the sheets, the two sets ofgripperslR (one setbeing carried by each section of the machine) willhave advanced and taken hold of the projecting ends of the sheets, theset of grippers carried by each section of the machine taking hold ofthe sheets carried by the other section of the machine, as clearly shownin Fig. 18. As these grippers are retracted-that is, moved away fromeach other from the position shown in Fig. 18s-*they will draw thesevered strips of one set in one direction and the severed strips of theother set in the opposite direction, thereby completing the operation ofinterlocking the strips of the filler. The grippers having beenretracted, an arm S, pivoted to one section of the machine, as shown atS', will be thrown down against the filler and not only knock it fromits position between the two sections of the machine, should it lodgethere, but also fold it, as indicated by the arrows in Fig. 2U. This armS is operated bya cam M2 on the wheel M engaging studs S2 projectingfrom the hub of the arm, as shown more clearlyin Figs. 1 and 2.

Each of the grippers comprises a pair of jaws having a normal tendencyto separate and having cam-surfaces which are adapted to engage withfixed parts for the purpose of closing the jaws during the act ofprojecting them. Preferably the jaws and the arms carrying them areconstructed of spring-wire bent to proper shape. As shown in thedrawings, each piece of wire entering into the construction of thesegrippers is bent at its middle to form an eye R5, which fits over a studO2, projecting from one of the cross-bars O of a rectangular frame O.This frame is preferably made of cast metal, and each of its cross-barsis provided with as many studs O2 as there are grippers in each set organg, and each cross-bar is also provided between the studs O2 withhooks O3, behind which hooks a removable pin or rod O4 is placed, sothat it engages the arms of the grippers in the vicinity of the eyes andholds the eyes in place on the studs O2. From the eyes R5 the two armsor branches of each piece of springwire diverge, so that theirextremities enter into the construction of adjacent pairs ofgripper-jaws. As shown at F', the back of each of the bars F is recessedto receive the arms of the gripper-jaws, and upon each of the bars F aremounted studs R2, which are preferably provided with antifrictiondevices disposed in position to engage cam-surfaces R2 on the jaws, andthereby cause the jaws to close as they are projected. Back of thecam-surfaces R2 the jaws or their stems are IOO IIO

provided with straight portions R4, which hold the jaws closed asufficient length of time to insure the complete interlocking of thefiller-strips as the jaws are being retracted. During this retractilemovement of the jaws, after the straight portions R4 have passed thestuds RS, the cam-surfaces R2 will permit the elastic arms of the jawsto separate them.

For the purpose of advancing and retracting the grippers the frame O isrigidly con.- nected to four rods P, which are sustained against lateraldisplacement and at the same time permitted to move freely endwise byguides P'. The extremities of these rods P are connected by means ofcouplings P with a pair of heavy transverse rods P2, the eX- tremitiesof .which occupy cam-grooves in a reciprocable cam-plate Q and arepreferably provided with antifriction devices. The camplates areconnected by means of bracketarms Q with the reciprocable rack-bars J4,so that the cam-plates partake of the movement of the rack-bars, and bythis means the feeding forward of the sheets and the advancing of thegri ppers take place simultaneously, the cam-grooves in the plates Qbeing so shaped that the grippers will reach the limit of their forwardmovement before the operation of feeding the sheets forward iscompleted, and thereafter the grippers will remain at rest until, duringthe return movement of the rack-bars J4, the oblique portions of thecam-slots in the plates Q reach the rods P2 and move them laterally,thereby retractin g the grippers. Referring again to Figs. 10 and l2, itwillbe seen that each of the bars Gis provided in its back withdepressions G7, which are disposed opposite the openings or matrices inthe bars F in position to receive the chips that are punched out of thestrawboard by the dies. From these depressions the chips are blown byjets of air discharged against them through ducts G9, leading to theopenings or matrices of the barF from a longitudinal channel G8 in saidbar, the extremities of said channel being suitably connected with apipe N, leading from some suitable blast apparatus. From the depressionsG7 the chips are blown into the space between one of the tubes or chutesI I and a flexible apron V, one edge of which is attached to the bar G,while the other edge rests upon a plate or diaphragm U, which isdisposed back of the reoiprocable gri pper-frame O and is continuous,save that it is providedwith slots, as shown in Fig. l2, for the passageof the sheets of strawboard. From these spaces, one for each set or gangof dies, the chips are blown by aircurrents directed into them from apipe N', located at the high side of the machine.
